• Design Considerations for Metal Injection Molding
  the cost of CNC machining or investment casting. Better yet, MIM allows the consolidation of multiple components into a single design, eliminating the need for downstream assembly operations. Finished parts have excellent strength, surface finish, and corrosion resistance. MIM material comprises fine...
• Direct Digital Manufacturing Part Two: Advantages and Considerations
  of DDM is that it removes constraints imposed by traditional manufacturing processes, such as injection molding or die casting. DDM fundamentally alters many of the "facts" and principles that govern conventional manufacturing enterprises. Since DDM is an additive process that eliminates tooling...
• High-performance hips
  size between a casting which has been sintered and a forging which was sintered. A CoCrMo Porocoat porous coated AML hip stem with a femoral head, articulating against the CoCrMo Ultamet metal-on-metal liner in a Pinnacle acetabular porous coated cup. Over 300,000 total hip replacements (THR) take...
• 12 Ways to Save

Most designers and engineers are familiar with the. to assure lowest casting costs. value of plastic molding part consolidations when. new molds are required. Similar consolidation...
• What Engineers Should Know about Direct Digital Manufacturing
  on workaday injection molding and casting. jobs. The hardware suppliers all claim they typically can hold +/- 0.002. inch/inch, so that smaller parts may tend to have somewhat better dimensional. accuracy. In reality, though, you will likely have to plan for finish machining to. achieve the critical...

  HIP. -3-. purpose-built equipment has enabled contract proces-. sors such as Howmet and Bodycote to provide cost. efficient casting densification for car makers and their. suppliers. For example, the special press built for Bodycote's. Densal® process features a short five-hour cycle, a. significantly...
• Rapid Manufacturing: Impact and Opportunity. Part 2, Freedom of Design
  Grimm & Associates, Inc. www.tagrimm.com. PREFACE. Rapid manufacturing is a process that employs additive fabrication technology (aka rapid prototyping) to. produce enduse items. Directly from CAD data, components are manufactured without molding, casting. or machining. The impact of rapid manufacturing...
• Refractory Metals
  and reflectors or radiation shields for high-temperature vacuum furnaces. Because it retains usable strength at elevated temperatures, has a low coefficient of thermal expansion, and resists erosion by molten metals, the TZM alloy is used for cores in die casting of aluminum, and for die cavities in casting...
• Tips for metal-to-plastic conversions
  that expected from a tool for casting aluminum. In most cases it takes numerous steps to turn a metal casting into a near-net shape. But a plastic component is usually ready to go right out of the mold. Many metal parts also need either a coating (paint, oil, etc.) or anodizing for corrosion protection...
